1 Initial Setup

1.1 Package Contents

 One RVI-600 (47860A-600)

 One Power Cable and Power Adapter

 Two Flanges and Mounting Screws

1.2 Operation

By default, the RVI-600 operates in S-TAC mode as a multi-link receiver voter in multicast mode. Receivers remain in

the idle state while detecting 2175Hz status tone from distant transceivers at -13dB. Upon the drop of the status tone

from any of these transceivers, the RVI-600 will begin the voting process.

Voting occurs when any of the un-squelched links achieve a higher signal-to-noise ratio (SNR) of 3dB or less from any

other link. This will lock in the channel as the preferred receiver and route audio to the default transmitter (TX1), the

console, and any connected TX pair on the designated RVI-600 TX/TX ports.

Voting elections remain available throughout the inbound transmission and if any other receiver achieves a higher SNR

value than the currently voted one, that channel will become the new voted channel.

1.3 Connecting the RVI-600 Voter

To configure the RVI-600 Voter for first use, access the RVI-600 using a PC and the supplied Ethernet cable. This

direct-connection procedure only needs to be done once. After this procedure, accessing the RVI-600 will be done

through the network and over any network port.

1. Refer to Figure 1-1 to connect the power cable, provided, to the AC input receptacle and then plug the other

end of the cable into the AC socket.

2. Connect the yellow ground tab, shown on the left, to the ground source for other equipment in the rack.

3. Connect a CAT 5 Ethernet straight network cable to the “network” port labeled, shown on the right. Connect

the other end to your network. The other ports, labeled TX 1, RX 1, RX/TX 2 through RX/TX 6, and Console

will be covered later in this guide.

2 Connections and Status Indicators

2.1 RVI-600 TX and RX Connections

Refer to Figure 2-1 for Connection descriptions.

TX1 is a default transmitter port. Voted audio is routed out of this port along with PTT or tone keying depending on

how the transmitter port is configured.

RX1 and RX/TX 2 through RX/TX 6 are receiver ports, or ports that vote. By default, all six are configured to vote on

loss of status tone (2175 Hz at -13 dB). Options for other status tones as well as to vote on COR detect are also

available with additional advanced setup which can be found in section 3.

RX 1 is a receiver port only but RX/TX 2 through RX/TX 6 are configured as combination transmitter and receiver

ports providing a multicast voting capability as needed.

The console port provides an input to any console as well as an output for voted audio. When the console port has

inbound audio it will be routed to the default transmitter (TX1).

If tone keying (default), the RVI-600 turns off its keying when console audio comes in and allows the keying

tone sequences from the console to key the transmitter. If relay keying, the transmitter port will provide the

PTT for keying of the radio when the console is active.

By default, the console has transmit priority for TX1 over any voted audio path. Console priority allows the dispatcher

to take priority over the transmitter from a port previously voted and using the transmitter

2.2 TX and RX Pin-Outs

The pin assignments for RX, TX, and Console ports (RJ45) is outline below.

Pin 1 RX A Input audio from Customer Equipment.

Pin 2 RX B Input audio from Customer Equipment. Note 1

Pin 3 PTT or M-Lead Out Output switch closure to customer equipment.

Pin 4 TX A Output audio to Customer Equipment.

Pin 5 TX B Output audio to Customer Equipment. Note 2

Pin 6 PTT or M-Lead Ground Return PTT ground return to customer equipment. Note 3

Pin 7 COR or E-Lead In Active low input from customer equipment. Note 4

Pin 8 COR or E-Lead Ground Ground connection to customer equipment.

Note 1: For unbalanced radio connections, this pin typically connects to a ground pin in the radio. Otherwise pins 1 &

2 are a balanced pair and polarity need not be observed.

Note 2: For unbalanced radio connections, this pin typically connects to a ground pin in the radio. Otherwise pins 4 &

5 are a balanced pair and polarity need not be observed.

Note 3: PTT is by default set for Active Closed (normally open) but can be changed to Active Open (normally closed).

Note 4: COR input by default is set for Active Low, but can be changed to Active High.

2.4 LED Status Indicators

As shown in Figure 2-2, there are seven LED’s. One for the transmitter and one for each receiver port. The LED’s

change colors to indicate the status of a particular port. There are four possible LED states.

Transmitter Status LED Status Indicator (refer to Figure 2-2)

Off = Idle

Red = Transmit

Voter Receiver Status LED Status Indicators (refer to Figure 2-2)

Red = Fault (RCVR)

This indicates a receive port fault. A fault condition can exist if a receiver port goes to un-squelch (loss of status

tone or COR detect) but no audio is detected for a period of time indicating a fault condition. For the transmitter

port the red LED indicates TX activity.

Green = Receive

This indicates a receive port has gone to the un-squelch condition (status tone drops or COR detected). There

is no green state indicator for the transmitter port.

Blue = Voted

This indicates a receive port is voted. There is no blue state indicator for the transmitter port.

Off = Idle

This indicates a squelch status (status tone being detected or no COR detected) on a receiver port. For the

transmitter port this indicates no TX activity.

3 Advanced Setup

3.1 Telnet Configuration

Additional parameters can be set via a telnet session. Use a telnet client such as putty (www.putty.org) or use the

Windows Telnet client. These settings are considered to be advanced and used in fewer voting environments. Use

with some caution or contact Raven for assistance. User credentials follow the same as configured through the web

interface.

Users can read or set configuration values using the following telnet commands (note that paths are case sensitive!):

setConfig – sets a value according to the tables below.

Example:

getConfig – gets a value according to the tables below.

Example:

Once a setting has been changed, a reboot command (“reboot”) must be initiated or simply power cycle the

device.

of the transmission and no other channel can be elected.

Individual channels also have their own vote period setting

which is set to 500ms by default and begins when this timer

expires.

3.3 Channel Specific Settings

Each receiver/transmitter channel has specific settings that can be manipulated via telnet. The configuration path for

each channel follows the format of {path}.{setting}:

Path = ravenInfo.m150.port[X]. where ‘X’ is channels 0 – 5.

To set the votedB on the first voter port one would use the following syntax:

Setconfig ravenInfo.m150.port[0].voteDB 2
